Abstract
A computer determines, based on a degree of authorization of a user, that a user has authorization to view a type of field. Based on the degree of authorization of the user, the computer generates a modified list of search terms by adding additional search terms to a list of search terms. The computer executes a search using the modified list of search terms. The computer identifies a search result that includes the first type of field which further includes a search term that is included in the modified list of search terms.
